This novel research, aimed to improve the properties of Na-bentonite water based drilling mud (WBDM) and reduce its cost by adding multi-walled carbon nanotubes functionalized with copper oxide nanoparticles (CuONPs/MWCNTs). For this purpose, fistly, copper oxide nanoparticles (CuONPs) and multi-walled carbon nanotubes (MWCNTs) were synthesized separately, then MWCNTs were functionalized with CuONPs by chemical vapor deposition (CVD) method. Secondly, CuONPs/MWCNTs were characterized by X-ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscopy (SEM). Thirdly, CuONPs/MWCNTs nanocomposite was added to the WBDM at different rates (0.001 to 0.01% w/v). Finally, rheological, filtration loss and cake thickness property analyzes were performed according to API standarts. As a result of this study, a significant improvement was observed in the rheological and filtration loss properties of WBDM with the addition of small amounts of CuONPs/MWCNTs. In particular, plastic visc...

CuONPs / MWCNTs对钠基膨润土水基钻井液性能影响的新研究及实验研究

这项新颖的研究旨在通过添加被氧化铜纳米颗粒（CuONPs / MWCNTs）功能化的多壁碳纳米管，来改善钠基膨润土水基钻井泥浆（WBDM）的性能并降低其成本。为此，首先，分别合成了氧化铜纳米颗粒（CuONP）和多壁碳纳米管（MWCNT），然后通过化学气相沉积（CVD）方法将MWCNT用CuONPs功能化。其次，通过X射线光电子能谱（XPS）和扫描电子显微镜（SEM）对CuONPs / MWCNTs进行了表征。第三，将CuONPs / MWCNTs纳米复合材料以不同的速率（0.001至0.01％w / v）添加到WBDM中。最后，根据API标准进行流变，过滤损失和滤饼厚度特性分析。这项研究的结果，通过添加少量的CuONP / MWCNT，可观察到WBDM的流变和滤失性能得到显着改善。特别是塑料粘胶...
